Secondary Characters and Motivation: A Study of Othello's Iago and A Doll's House Krogstad. This essay compares the characters of Iago, from Othello, with Krogstad in A Doll's House. These two men play significant roles in destroying a marriage; however, the results of their involvement are different. Iago ruins Othello and instigates the murder of Othello's wife. Krogstad inadvertently liberates Nora from her marriage so that she is free to leave her unhappy life. While both Iago and Krogstad are secondary characters, they play primary roles in effecting a dramatic change in the outcome of the plays. 5 pgs. Bibliography lists 2 sources.
